37 children of functional amblyopia and 40 normal children were examined with the multi-channel VEP topography by full field pattern reversal stimulation. The average results of esotropia showed a "half field stimulation effect", or an asymmetric distribution, in the amblyopic eyes, and a minor "half field stimulation effect" also existed in the nonamblyopic fellow eyes. However, the "half field stimulation effect" did not appear in both the amblyopic and non-amblyopic fellow eyes in anisometropic amblyopia. The findings suggest that (1) the pathological mechanism may be different between esotropic and anisometropic amblyopia, and (2) the non-amblyopic eye in esotropic amblyopia may not actually be "normal".
对37例功能性弱视儿童和40例正常儿童进行了全视野图形翻转刺激下的多通道视觉诱发电位地形图检查。内斜视的平均结果显示，弱视眼存在“半视野刺激效应”，即不对称分布，非弱视的对侧眼也存在轻微的“半视野刺激效应”。然而，屈光参差性弱视的弱视眼和非弱视对侧眼均未出现“半视野刺激效应”。这些发现表明：（1）内斜视性弱视和屈光参差性弱视的病理机制可能不同；（2）内斜视性弱视的非弱视眼实际上可能并不“正常”。
